JP 2009-57687 A

  However, in the above method, it is necessary to provide a mounting hole and slit at the end of the operating shaft, but the processing for providing the mounting hole and slit on the metal operating shaft is not easy. . In particular, it is difficult to form the slit portion in which the transmission member is disposed due to a relatively narrow width. For this reason, there is a risk of increasing manufacturing costs and reducing productivity.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an operation device capable of reducing the manufacturing cost and improving the productivity while allowing the operation shaft and the transmission member to be easily connected. There is to do.

  In the following, each means suitable for solving the above-described object will be described in terms of items. In addition, the effect specific to the means to respond | corresponds as needed is added.

Means 1. A cylindrical guide member;
A reciprocating operation shaft inserted through the inner periphery of the guide member;
A transmission member for transmitting the driving force due to the displacement of the operation shaft to the plug lid side provided at the drainage port of the tank body;
A terminal connection part attached to the outer periphery of the end of the transmission member and protruding from the outer periphery of the transmission member;
At the end of the operating shaft,
A mounting hole configured to have a mounting opening through which the terminal connection portion can pass on an outer peripheral surface of the end portion, and the terminal connection portion can be disposed through the mounting opening;
A slit opening portion through which the transmission member can pass is formed on the outer peripheral surface, and a slit portion configured to communicate with the mounting hole portion and to be able to arrange the transmission member through the slit opening portion is formed. And
The operation in which the transmission member is arranged in the slit portion, the terminal connection portion is arranged in the mounting hole portion, and the operation shaft and the transmission member are connected. A device,
The operation axis is
A rod-shaped shaft body made of metal;
An operating device connected to an end portion of the shaft main body portion and having a resin-made terminal portion formed with the mounting hole portion and the slit portion.

  According to the means 1, it is possible to easily connect the operation shaft and the transmission member by a simple method of arranging the terminal connection portion in the mounting hole portion while arranging the transmission member in the slit portion.

  According to the first aspect of the present invention, the operation shaft includes a resin terminal portion, and a mounting hole portion and a slit portion are formed in the terminal portion. Therefore, compared to the case where the mounting hole and slit are provided in the metal part, the processing for providing the mounting hole and slit can be facilitated, and the slit is difficult to form. Can also be easily provided. Thereby, reduction of manufacturing cost and improvement of productivity can be aimed at.

  Mean 2. 2. The operating device according to claim 1, wherein the terminal portion has a bottom portion that prevents the terminal connecting portion disposed in the mounting hole from slipping out to the side opposite to the mounting opening.

  The “bottom part” is not limited to the one that can prevent the terminal connection part from coming off, and is not limited to the one that closes the mounting hole on the opposite side of the mounting opening. Therefore, the “bottom part” is, for example, a protrusion (step) part protruding toward the inside provided on the inner peripheral surface of the part forming the mounting hole, or a bridge-shaped part connecting the inner peripheral surfaces facing each other. It may be.

  For example, it is conceivable that the mounting hole portion has a shape with a bottom that passes through the terminal portion. However, in this case, there is a risk that the terminal connection part may fall out of the mounting hole when the terminal connection part is disposed in the mounting hole through the mounting opening, and the assembly work is not performed. It becomes necessary to do it carefully.

  In this regard, according to the means 2, the terminal portion has a bottom portion, and the bottom portion prevents the terminal connection portion disposed in the mounting hole portion from slipping out to the side opposite to the mounting opening portion. Can do. Accordingly, when the terminal connection portion is disposed in the mounting hole through the mounting opening, the terminal connection portion does not fall out of the mounting hole. Thereby, assembly work can be performed more easily and productivity can be further improved.

  Means 3. The operating device according to means 1 or 2, wherein the terminal portion has an escape portion in which the outermost portion of the transmission member can be arranged.

  According to the above means 3, the terminal portion is formed with a relief portion (escape space) where the outermost end portion of the transmission member can be arranged. Therefore, even when the outermost end portion of the transmission member protrudes from the terminal connection portion, the outermost end portion does not hinder the placement of the terminal connection portion into the mounting hole. Therefore, the state where the end of the transmission member protrudes from the terminal connection portion may remain. Accordingly, it is necessary to perform a processing process (for example, a process of cutting the outermost part protruding from the terminal connection part and then cutting) so that the outermost part of the transmission member does not protrude from the terminal connection part. Disappear. Further, it is not necessary to prepare expensive equipment or the like for performing the processing. As a result, the manufacturing cost can be reduced and the productivity can be improved more effectively.

  In addition, although it is difficult to form a relief part in a metal part similarly to the case where a slit part is formed in a metal part, since the terminal part is made of resin, the relief part can be easily formed. That is, making the terminal portion made of resin is effective even when the configuration of the means 3 is adopted.

  Means 4. Any of the means 1 to 3, wherein the length of the mounting hole portion along the axial direction of the operation shaft is the same as the length of the terminal connection portion along the axial direction of the transmission member. The operation device according to the above.

  Note that “same” is not only strictly the same, but also almost the same (for example, the portion where the mounting hole is formed to such an extent that a good operation response can be ensured). This includes the case where a slight gap is formed between the terminal connection portion and the like.

  According to the means 4, the length of the mounting hole along the axial direction of the operation shaft is the same as the length of the terminal connecting portion along the axial direction of the transmission member. Therefore, the relative movement of the terminal connection portion with respect to the terminal portion along the axial direction of the operation shaft can be restricted. That is, there can be almost no rattling along the axial direction of the operation axis between the terminal unit and the terminal connection unit. Therefore, the driving force due to the displacement of the operation shaft can be more reliably transmitted to the transmission member without loss, and the operation timing of the transmission member can be more reliably prevented from being delayed with respect to the operation timing of the operation shaft. As a result, the operation response can be increased, and the operability can be improved.

  In addition, when the length of the mounting hole is the same as the length of the terminal connecting portion, when the outermost end portion of the transmission member protrudes from the terminal connecting portion, the outermost end portion is accommodated in the mounting hole portion. However, there is a concern that the arrangement of the terminal connection portion with respect to the mounting hole portion may be hindered. However, by adopting the above means 3, such a concern can be eliminated. Therefore, when the configuration of the means 4 is adopted, it is preferable to adopt the configuration of the means 3 together.

The guide member 2 includes a cylindrical guide main body 21 and a flange 22 that protrudes from one end of the guide main body 21 to the outer periphery. On the outer periphery of the guide main body portion 21, a first male screw portion 21A located on one end side (the flange portion 22 side) and a second male screw portion 21B located on the other end side are formed.

  The nut member 3 is used for fixing the guide member 2 to the flange portion 101. The nut member 3 has an annular shape, and has a first female screw portion 3A on the inner periphery that can be screwed with the first male screw portion 21A. Then, after inserting the guide member 2 into the through hole 102, the first male screw portion 21 </ b> A is screwed into the first female screw portion 3 </ b> A, and the flange portion 101 is sandwiched between the flange portion 22 and the nut member 3. A guide member 2 is attached to the portion 101. A predetermined packing (not shown) is disposed between the flange portion 22 and the flange portion 101 (for example, an annular groove provided on the back surface of the flange portion 22), and the packing is sandwiched between the flange portion 22 and the flange portion 101. Further, it may be possible to prevent water from entering between the flange portion 222 and the flange portion 101.

  The operation member 4 is used when opening and closing a drain (not shown) of the basin 100. The operation member 4 is inserted into the inner periphery of the guide member 2 and is screwed to a rod-shaped operation shaft 41 that can be reciprocated along the inner periphery of the guide member 2 and one end of the operation shaft 41. And a knob 42 for operation.

  The transmission member 5 is connected to the other end portion of the operation shaft 41, and the operation shaft 41 and the transmission member 5 are reciprocated by pushing and pulling the knob portion 42. Further, an annular seal member 9 made of an elastically deformable material is provided between the outer peripheral surface of the operation shaft 41 and the inner peripheral surface of the guide member 2 in a state of being sandwiched between both surfaces. The seal member 9 prevents leakage of water that has entered between the operation shaft 41 and the guide member 2 to the transmission member 5 side. The detailed configuration of the operation shaft 41 and the connection mode of the transmission member 5 to the operation shaft 41 will be described later.

  The transmission member 5 is composed of, for example, a wire or the like, and transmits the driving force due to the displacement of the operation shaft 41 to the side of the stopper lid (not shown) provided in the drain (not shown) of the washbasin 100. To do. The transmission member 5 is disposed on the inner periphery of the tubular tube member 7 and reciprocates relative to the tube member 7 with the displacement of the operation shaft 41. In addition, the flare part 71 which protrudes to the radial direction outer side formed by the flare process etc. is provided in the edge part of the tube member 7. FIG.

  Moreover, the edge part of the transmission member 5 is exposed from the edge part of the tube member 7, and the hook-shaped terminal connection part 8 which protrudes from the said outer periphery is engage | inserted by the outer periphery of this edge part. In the present embodiment, the outermost end portion of the transmission member 5 is in a state of protruding from the terminal connection portion 8.

  The closing member 6 is attached to the guide member 2 and has a function of preventing the operation member 4 from protruding from the other end of the guide member 2 while holding the end portion of the tube member 7. The closing member 6 includes a lid part 61 and a holding part 62.

  The lid portion 61 is provided at a position that closes the opening on the other end side of the guide member 2, and prevents the operation member 4 from protruding from the other end of the guide member 2. The lid 61 is formed in a cylindrical shape by combining a pair of halves (for example, one half is locked to the other half). An insertion hole 61A extending in the central axis direction is provided. The insertion hole 61 </ b> A is an arrangement space for the transmission member 5 and the tube member 7, and a groove-like flare arrangement extending in the circumferential direction of the insertion hole 61 </ b> A is provided at a substantially central portion of the insertion hole 61 </ b> A along the central axis of the lid portion 61. A portion 61B is formed. And the said flare part 71 is arrange | positioned with respect to the flare arrangement | positioning part 61B. Thereby, the edge part of the tube member 7 is hold | maintained by the cover part 61 in the state in which the removal from the cover part 61 along an own axial direction was controlled.

  The holding portion 62 holds the lid portion 61 at a position where the other end opening of the guide member 2 is closed. The holding part 62 has a cylindrical shape, and a second female screw part 62A located on one end side and a step part 62B located on the other end side are formed on the inner periphery thereof. The second male screw portion 62B is screwed into the second female screw portion 62A. As a result, the closing member 6 is attached to the guide member 2. The step portion 62B is an annular protrusion that protrudes toward the central axis of the holding portion 62, and the lid portion 61 is locked to the step portion 62B. The step portion 62 </ b> B holds the lid portion 61 by sandwiching the lid portion 61 with the guide member 2. In addition, since the opening on the outer peripheral side of the lid portion 61 in the insertion hole 61A is closed by the holding portion 62 disposed on the outer periphery of the lid portion 61, the flare portion 71 does not come off from the flare arrangement portion 61B.

  Next, a detailed configuration of the operation shaft 41 and a connection mode of the transmission member 5 to the operation shaft 41 will be described. As shown in FIGS. 1 and 2, the operation shaft 41 includes a shaft main body portion 411 and a terminal portion 412.

  The shaft body 411 is formed in a rod shape (columnar shape) from a predetermined metal (for example, a metal having excellent corrosion resistance), and the knob portion 42 is attached to one end thereof. Further, a shoulder portion 411A, a neck portion 411B, and a head portion 411C are formed in this order on the other end portion of the shaft main body portion 411 toward the other end side. The shoulder portion 411A and the head portion 411C are formed with a larger diameter than the neck portion 411B.

  Unlike the shaft main body 411, the terminal 412 is made of a predetermined resin. The terminal portion 412 has a shape such that two dents are formed side by side along its own axial direction. The neck arrangement portion 412A and the head arrangement portion 412B forming one dent, and the other dent are formed. An escape portion 412C, a mounting hole portion 412D, and a slit portion 412E are provided.

  The neck placement portion 412 </ b> A has a width corresponding to the outer diameter of the neck portion 411 </ b> B and opens at one end surface of the terminal portion 412. The head placement portion 412B is adjacent to the neck placement portion 412A and has a width corresponding to the outer diameter of the head 411C. A neck portion 411B is arranged with respect to the neck arrangement portion 412A, and a head portion 411C is arranged with respect to the head arrangement portion 412B. Thereby, the shaft main body 411 and the terminal 412 are connected.

  In this embodiment, the length of the neck placement portion 412A along the axial direction of the terminal portion 412 is the distance between the shoulder portion 411A and the head portion 411C along the axial direction of the shaft main body portion 411 (that is, the neck portion 411B). Is approximately equal to the length). Therefore, in a state where the shaft main body portion 411 and the terminal portion 412 are connected, a portion forming the neck arrangement portion 412A in the terminal portion 412 is in contact with both the shoulder portion 411A and the head portion 411C and is sandwiched between the two. It has become. As a result, relative movement of the terminal portion 412 with respect to the shaft main body portion 411 along the axial direction of the operation shaft 41 is restricted, and as a result, force is transmitted from the shaft main body portion 411 to the terminal portion 412 without loss. .

  The escape portion 412C is a space having a width corresponding to the outer diameter of the portion of the transmission member 5 that protrudes from the terminal connection portion 8 (that is, the endmost portion of the transmission member 5).

  The mounting hole 412D is a space having a mounting opening 412F (see FIG. 2) corresponding to the outer periphery of the terminal portion 412. The mounting hole 412 </ b> D has a width corresponding to the outer diameter of the terminal connection portion 8. Further, the length of the mounting hole 412 </ b> D along the axial direction of the operation shaft 41 is the same as the length of the terminal connection portion 8 along the axial direction of the transmission member 5.

  Furthermore, the mounting hole portion 412D has a shape that does not penetrate the terminal portion 412, and the side opposite to the mounting opening portion 412F in the mounting hole portion 412D is closed. That is, the terminal portion 412 includes a bottom portion 412H (see FIG. 2) corresponding to the bottom of the mounting hole portion 412D.

  The slit portion 412E is a space having a slit opening 412G (see FIG. 2) corresponding to the outer periphery of the terminal portion 412. The slit portion 412 </ b> E has a width corresponding to the transmission member 5 and opens at the other end surface of the terminal portion 412.

Then, the end portion of the transmission member 5 and the terminal connection portion 8 are disposed in the escape portion 412C, the mounting hole portion 412D, and the slit portion 412E. That is, the outermost end portion of the transmission member 5 is disposed with respect to the relief portion 412C, the terminal connection portion 8 is disposed with respect to the mounting hole portion 412D, and the opposite end portion of the transmission member 5 is opposite to the slit portion 412E. On the side, a portion adjacent to the terminal connection portion 8 is arranged. Thereby, the transmission member 5 is connected to the operation shaft 41. The terminal connecting portion 8 disposed in the mounting hole 412D is prevented from coming out on the side opposite to the mounting opening 412F due to the presence of the bottom portion 412H. The openings of the neck arrangement part 412A and the head arrangement part 412B, the relief part 412C, the mounting hole part 412D and the slit part 412E) are closed by the guide member 2, respectively. Therefore, the terminal part 412 is not detached from the shaft main body part 411, and the transmission member 5 and the terminal connecting part 8 are not detached from the operation shaft 41 (terminal part 412).

  The terminal unit 412 can be obtained by, for example, molding using a predetermined mold.

  Next, a method for attaching the operation device 1 to the washbasin 100 will be described.

  First, after the guide member 2 is inserted into the through hole 102, the inner periphery of the nut member 3 is brought into contact with the first male screw portion 21 </ b> A through the guide member 2 from the other end side of the guide member 2. In this state, by rotating the nut member 3, the first male screw portion 21 </ b> A is screwed with the first female screw portion 3 </ b> A, and the flange portion 101 is sandwiched between the flange portion 22 and the nut member 3. Thereby, as shown in FIG. 3, the guide member 2 is attached to the flange portion 101.

  Next, after the seal member 9 is arranged on the outer periphery of the shaft main body 411, the shaft main body 411 is inserted into the inner periphery of the guide member 2 from the other end side opening to some extent, and at least the neck 411B of the shaft main body 411 is inserted. The head 411C protrudes from the other end of the guide member 2. Then, the terminal portion 412 is connected to the shaft main body portion 411 by disposing the head portion 411C on the head disposing portion 412B. Further, the terminal connection portion 8 is disposed in the mounting hole portion 412D through the mounting opening portion 412F, and the transmission member 5 is disposed in the slit portion 412E through the slit opening portion 412G, thereby transmitting the transmission member to the terminal portion 412. 5 is connected. At this time, the most distal portion of the transmission member 5 is disposed to the escape portion 412C. In addition, before connecting the transmission member 5 to the terminal portion 412, the halved portions constituting the lid portion 61 are combined so as to sandwich the flare portion 71, and the flare portion 71 is arranged in the flare arrangement portion 61B. The lid portion 61 is disposed on the outer periphery of the member 7, and the transmission member 5 and the tube member 7 are passed through the inner periphery of the holding portion 62, so that the lid portion 61 and the holding portion 62 are previously disposed outside the transmission member 5 and the like. It is said that it was in the state.

  Then, as shown in FIG. 4, the terminal portion 412 is inserted through the inner periphery of the guide member 2. Thereby, two dents (head arrangement part 412B, mounting hole part 412D, etc.) in terminal part 412 are obstructed by guide member 2, and as a result, axis body part 411, terminal part 412 and transmission member 5 are adjacent. It will be in the state connected in series, without parts separating.

  Before inserting the shaft main body 411 into the guide member 2, the shaft main body 411, the terminal 412 and the transmission member 5 are connected in series, and then the shaft main body 411 and the terminal 412 are connected to the guide member 2. It may be inserted into the inner circumference of the.

  Next, the holding portion 62 previously arranged on the outer periphery of the transmission member 5 and the like is moved to the nut member 3 side to lock the lid portion 61 to the stepped portion 62B, and the inner periphery of the holding portion 62 and The second male screw portion 21B is brought into contact. Then, by rotating the holding portion 62, the second male screw portion 21 </ b> B is screwed with the second female screw portion 62 </ b> A, and the holding portion 62 is attached to the guide member 2. As a result, as shown in FIG. 5, the lid 61 is sandwiched between the guide member 2 and the stepped portion 62 </ b> B, and the tube member 7 is held by the closing member 6 (the lid 61 and the holding portion 62). The other end side opening is closed. In addition, before attaching the holding | maintenance part 62 with respect to the guide member 2, a transmission member 5 is matched with the attachment process of the holding | maintenance part 62 with respect to the guide member 2, without previously arrange | positioning the cover part 61 and the holding | maintenance part 62 on outer periphery, such as the transmission member 5. You may arrange | position the cover part 61 and the holding | maintenance part 62 in outer periphery, such as 5.

  Finally, the knob portion 42 is screwed to one end portion of the shaft main body portion 411 protruding from the guide member 2. As a result, the attachment of the operating device 1 to the washbasin 100 is completed.

  As described in detail above, according to the present embodiment, the operation shaft 41 and the transmission are transmitted by a simple method of arranging the terminal connection portion 8 in the mounting hole 412D while arranging the transmission member 5 in the slit portion 412E. The member 5 can be easily connected.

  Further, the operation shaft 41 includes a resin terminal portion 412, and a mounting hole portion 412 </ b> D and a slit portion 412 </ b> E are formed in the terminal portion 412. Therefore, the processing for providing the mounting hole 412D and the slit portion 412E can be made easier compared with the case where the mounting hole and the slit portion are made of metal parts. Even the difficult slit 412E can be easily provided. Thereby, reduction of manufacturing cost and improvement of productivity can be aimed at.

  In addition, since the bottom portion 412H exists, when the terminal connection portion 8 is disposed in the mounting hole portion 412D, the terminal connection portion 8 does not fall out of the mounting hole portion 412D. Thereby, assembly work can be performed more easily and productivity can be further improved.

  Further, the length of the mounting hole 412 </ b> D along the axial direction of the operation shaft 41 is the same as the length of the terminal connection portion 8 along the axial direction of the transmission member 5. Therefore, the relative movement of the terminal connection portion 8 with respect to the terminal portion 412 along the axial direction of the operation shaft 41 can be restricted, and the axial direction of the operation shaft 41 is between the terminal portion 412 and the terminal connection portion 8. It can be in a state where there is almost no rattling. Therefore, the driving force due to the displacement of the operation shaft 41 can be more reliably transmitted to the transmission member 5 without loss, and the operation timing of the transmission member 5 is more reliably delayed with respect to the operation timing of the operation shaft 41. Can be prevented. As a result, the operation response can be increased, and the operability can be improved.

  In this embodiment, since the length of the neck arrangement portion 412A is substantially equal to the distance between the shoulder portion 411A and the head portion 411C, the terminal portion 412 with respect to the shaft main body portion 411 along the axial direction of the operation shaft 41. Relative movement can be restricted. Therefore, operability can be effectively improved in combination with the above-described effects.

  On the other hand, if the length of the mounting hole 412D is the same as the length of the terminal connection portion 8, the outermost end of the transmission member 5 protrudes from the terminal connection portion 8 as in the present embodiment. Although it is feared that the end portion cannot be accommodated in the mounting hole portion 412D and the arrangement of the terminal connection portion 8 with respect to the mounting hole portion 412D is hindered, in this embodiment, the terminal portion 412 has Is formed with an escape portion 412C for disposing the outermost end portion of the transmission member 5. Therefore, the end of the transmission member 5 does not become a hindrance when the terminal connection portion 8 is disposed in the mounting hole 412D. Thereby, the state in which the endmost part of the transmission member 5 may protrude from the terminal connection part 8 may be kept, and the processing (for example, to prevent the endmost part of the transmission member 5 from protruding from the terminal connection part 8) It is not necessary to perform a cutting process after cutting the outermost portion protruding from the terminal connection unit 8. Further, it is not necessary to prepare expensive equipment or the like for performing the processing. As a result, the manufacturing cost can be reduced and the productivity can be improved more effectively.

  It is difficult to form the relief portion in the metal part, as in the case of forming the slit portion in the metal part. However, since the terminal portion 412 is made of resin, the relief portion 412C can be easily formed. it can. That is, making the terminal portion 412 made of resin is effective in forming the escape portion 412C.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, the bottom 412H is provided so as to close the mounting hole 412D, but the bottom prevents the terminal connection portion 8 from coming off to the side opposite to the mounting opening 412F. What is necessary is just to be able to do, and it does not necessarily need to block the mounting hole 412D. Accordingly, the bottom portion is, for example, a protrusion (step) portion protruding toward the inside provided on the inner peripheral surface of the part forming the mounting hole 412D, a bridge-shaped portion connecting the inner peripheral surfaces facing each other, or the like.
